Crin3

This is a 512M RAM Debian Stretch server for running S3QL and doing backups, it was installed on see ticket:11.

Retrieving backups

Backup process

There is a root crontab which runs the backups each night:

# m h  dom mon dow   command
01 01 * * * umnt-s3ql crin1 ; mnt-sshfs crin1 ; s3ql_backup crin1
01 02 * * * umnt-s3ql crin2 ; mnt-sshfs crin2 ; s3ql_backup crin2
01 03 * * * umnt-s3ql crin4 ; mnt-sshfs crin4 ; s3ql_backup crin4

First the S3QL file system is unmounted and checked (in case it has been manually mounted during the day) via wiki:S3QLMnt#unmnt-s3ql, then the remote server is mounted via SSHFS using wiki:SshfsMnt#mnt-sshfs and then the backup is run using a modified version of the ​S3QL backup script, wiki:S3QLBackup#s3ql_backup which calls the ​expire_backups script to delete old backups.
